This invention relates to a chock-designed for use on the bolster of a Wagon or other vehicle and which, when in position, will prevent logs andsimilar articles [from rollio ing' off of the bolster on which they are mounted. One of the objects of the invention is to provide simple and 'efiicient means for at.- taching the chock to the bolster, said means being so constructed as to permit the chock W to be removed readily when not inuse.

A further object .is to provide a chock I which is simple, durable and efficient and can be easily applied." 7 I With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the.

details of construction hereinafter described 2 and claimed, it being understood that changes in the preciseflembodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit 'of the invention. 7 In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, V

Figure 1 is anjend elevation of the chock,

the bolster to which it is attached being 80 shown in section. V

Figure 2 is an elevation of one side of the chock and of the adjacent portion of the bolster supporting the same.

Figure 3 is a view similar to Figure 2 showingthe other side of the chock and a portion ofthe bolster. Referring to the figures by characters'of reference 1 designates a block constituting the body portion of the chock, this block 0 being formedwith a beveled end 2 and being adapted to rest flat upon the top surface of a bolsterB. The bolster is formed with a transverse key hole aperture C. Se-

cured loosely to the sides of the block 1 are straps 3, these straps being held to the block by a bolt 4 extending transversely therethrough. One of the straps 3 is formed, near its lower end, with an aperture 5 preferably circular while the other strap 3 has a key hole slot 6 therein. Both of the apertures 5 and 6 are adapted to register with the ends of the opening C. I

An attaching pin 7 is provided for holding the chock to the bolster. This .pin has one into the opening!) whereuponv the pin is from the slot G and then, by turning the slot extending therethrough, of a chock inend reduced in diameter as shownat 8 and ofiset to provide aradial lug 9; Extending from the other end of the pin is a crank arm 10. g V

Whenitis desired to apply the chock to a bolster, the same is placed in position thereon with the straps3 extending along opposite sides of the bolster, as shown. The pm 7 is then arranged substantially vertically so thatthe end ofthe lug'9 can be inserted ,65 swung through an angle'and slid longitudinally of the aperture 0. The lug 9 may pass,

through the'slot 6 after being turned into alinement therewithsubsequent to emerging crank arm 10, the lug will turn downwardly to the position shown in Figures 1 and i3, thereby preventing the pin from being withdrawn from engagement with the parts.

Itwillbe apparent that when the parts are assembled as described the chock will be f held securely tothe bolster andwhen this chock is arranged with its beveled 'or inclined end innermost, it will constitute a rest or abutment for logs or thelike supported by the bolster. The pressure of the'logs 4 will tend to thrust the chock. outwardly but 1 this outward movement will be limited by p the straps 3 with the result that the parts will be bound tightly together and cannot s 1p. a a For the purpose of removing the chock from .thebolster the crank 10 is provided so, that the .pin 7 can be rotated to-swing the 7 lug 9 upwardly. The pin is then withdrawn from engagement with the slotted strap 3 after which it is'swung downwardly to permit withdrawal of the lug from the opening 5. As the crank 10 normally hangs down: wardly, it tends normally to hold the parts securely fastened together so thattheywill not become accidentally disconnected.

What is claimed is: f The combination with a bolster having a eluding a b1ock, straps pivotally connected to the sides of the block and extending through the side'of the-bolster, there being an aperture in one of the straps adapted to register with a portion of the chock in the bolsterand a slot in the other strap'adapted to register with av portion of the slot in. the

bolster a pin having an ofi'set .lug extending V i radiallyfrom one end portion thereof, said same tosaid position said arm constituting lug being insertable through the aperture in means for holdingthe lug normally onto one of thestraps, rotatable to position for alinement With the slot in the strap. 10

insertion through the slot in .thebolster, In testimony that I'olaim the foregoing as I I 5 and then rotatable to position for insertion my. own, I have hereto aflixed my signature; through the slot in the other strap, and an r v arm extending from the pin for rotating the ANDREW S. HUNT.
